Issue with AJAX compatibility in Internet Explorer

I have been successfully implementing Ajax in my application across various browsers, however, I am encountering issues with Internet Explorer. Below is the code that I have developed - could you please review it and provide guidance on where I might be making a mistake? Here's the code:

<script type="text/javascript>
  function loadXMLDoc(str) {
    document.getElementById('spinner').style.display = "block";

    if (str == "") {
      document.getElementById("pickZone").innerHTML = "";
      document.getElementById('spinner').style.display = "none";
      return;
    }

    if (window.XMLHttpRequest) {
      xmlhttp = new XMLHttpRequest();
    } else if (window.ActiveXObject) {
      try {
        xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
      }
      catch (e) {
        try {
          xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }
        catch (e) {
          xmlhttp = false;
        }
      }
    }

    xmlhttp.onreadystatechange = function () {
      if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
        document.getElementById('spinner').style.display = "none";
        document.getElementById("pickZone").innerHTML = xmlhttp.responseText;
      }
    }

    xmlhttp.open("GET", "getPickZone.jsp?q=" + str, true);
    xmlhttp.send();
  }
</script>

Answer №1

For those open to using jQuery, a simple solution would be:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
function retrieveData(str) {
  $('#spinner').css({visibility:"visible"});
  $('#pickZone').html('');
  if (str != '') {
    $.ajax({
      type: "GET",
      url: "getPickZone.jsp",
      data: {q:str},
      success: function(xml) {
        $('#spinner').css({visibility:"hidden"});
        $('#pickZone').html(xml);
      }
    });
  }
}
</script>

This approach could streamline the code and address any compatibility concerns.

Answer №2

It is recommended to use xmlhttp.send(null) rather than xmlhttp.send() for better functionality.

xmlhttp = new ActiveXObject("MsXML2.XMLHTTP");

In addition, consider using the following: 

MsXML[i] where i can be any number from 1 to 5 and so on.
